What is onetime

onetime is:

OneTime is an encoder/decoder that uses the one-time pad algorithm.

OneTime is a simple one-time pad encryption program that takes care of some of the pad-management bureaucracy for you. It avoids re-using pad data (except when decrypting the same encrypted message twice, of course) by maintaining records of pad usage.

If you keep your ~/.onetime configuration area under version control with Subversion or CVS, OneTime will automatically update it to get the latest pad usage records before using a pad, and will commit new records after using a pad. Thus, by sharing a single configuration area via version control, you and your interlocutors can more easily avoid the sin of pad range reuse.
